Item Agronomical characteristics the breeding germplasm of chickpea [Articol](Editura USM, 2025) Curshunji, DmitriInvestigation material comprised twenty(F5) and eight ten (F3) breeding germplasm of chickpea derived from 2 crosses ♀Alexandrite×♂Ichel and ♀Botna×♂Ichel respectively, as check was v. Botna. The objective of the study was evaluation and selection germplasm by yield and analysis 5 yield attributing characters: number seeds and seeds yield per plant, hundred seeds weight, plant height and full maturity. Method of breeding is "pedigree". By productivity were selected 10(F4) and 12(F5) progenies, of them B121, B144, B126, B130, B137, B143, B147 and A170, A181, A190 were evaluated as high yielded (116.1 – 124.2g/m2), which superior the check v. Botna (106.5g/m2). Analysis of traits revealed that no. of seeds and seeds yield per plant are principal in yield enhancing. Larger seeds germplasm coupled with taller plant for most progenies increases yield per plant. Most high yielded germplasm is middle-maturity. Strong relationship exhibited trait seeds yield per plant with plant height (r=0.855), hundred seeds weight (r=0.881) and with no. seeds per plant (r=0.891) in F4 and F6 generation, respectively.Item Productivity indices in Lavandula Angustifolia mill. Varieties, sixth year of vegetation [Articol](Editura USM, 2025) Butnaraș, Violeta; Balmuș, Zinaida; Cotelea, LudmilaThe evaluation of quantitative character indices – lant height and diameter, number of flowering stems per plant, inflorescence and floral spike length, number of whorls on the floral spike, raw material yield, and essential oil content – allowed for the characterization and assessment of each lavender variety-clone. The varieties under study synthesized and accumulated an essential oil content at standard humidity (60%) exceeding 2% (Svetlana – 2.199%; Alba 7 – 2.188%), and on dry matter basis exceeding 5% (Svetlana – 5.498%; Alba 7 – 5.472%). Raw material yield varied from 3.6 t/ha to 7.7 t/ha depending on the variety, with the most productive being Svetlana (7.7 t/ha), Alba 7 (7.3 t/ha), and Favoare (6.7 t/ha). The essential oil yield in the evaluated varieties-clones ranged from 11.6 kg/t to 22.0 kg/t. The highest yields were recorded in the varieties: Svetlana (22.0), Alba 7 (21.8), and Favoare (17.1) kg of essential oil per ton of fresh inflorescences.Item Ranks and rank stability of wheat cultivars tested in national yield trials in Romania [Articol](Editura USM, 2025) Marinciu, Cristina Mihaela; Șerban, Gabriela; Mandea, Vasile; Galit, Indira; Saulescu, NicolaeCultivars can play a key role in ensuring high wheat grain yields and reducing its variation under the increasing environmental variability. We used data on grain yield and coefficients of variation from sixty yield trials with Romanian winter wheat cultivars, conducted in four regions of the country, for four years (2021-2024) to analyze the ranks and rank variances of the tested cultivars. Despite the large variation of environments, we identified cultivars with better average ranks and with lower rank variances, which could contribute to higher and more stable yields in farms. Results are also useful for establishing priorities in breeding future cultivars.Item Assessment of correlation and path analysis in collection’s genotypes of chickpea(CEP USM, 2024) Curshunji, DmitriTwenty three collection genotypes of chickpea were evaluated for 10 components of yield (3 phenological and 7 plant data) on grain yield per plant. Investigation was carried out on field of Institution in 2022-2023. Correlation analysis revealed significant relationship by characters: days taken to flowering and maturity, primary and secondary branches per plant and 100 grain weight with grain yield. Highly negative correlation with yield had component grain per pod. Path analysis revealed direct effect on yield following components: highest effect had character 100 grain weight (0.833) followed by pods per plant (0.562), days to flowering (0.362), primary branches per plant (0.192) and secondary branches per plant (0.074). Highest negative direct effect on yield had character grain per pod (-0.881) followed by grain per plant (-0.593), days taken to maturity (-0.106). Grain per plant was formed mainly on basis 6 components by indirect effects.Item Manifestation of heterosis in cucumber F1 hybrids according to yield indicators in the forest-steppe conditions of Ukraine(CEP USM, 2024) Serhiienko, Oksana; Solodovnyk, Lina; Harbovska, Тetiana; Radchenko, LarisaThe conducted research evaluated the effect of heterosis and the degree of dominance of promising hybrid combinations of cucumber. Twenty-eight hybrid combinations were analyzed for four yield traits: total and marketable yield, yield in the first decade of fruiting, marketable percentage, and average fruit weight. It was established that the effect of heterosis varied depending on the combination of crossing and the investigated trait. The trend of a positive relationship between the values of heterosis and the degree of dominance was revealed: an increase in the degree of dominance was accompanied by an increase in the effect of heterosis. The highest heterosis effect was noted in F1 hybrid combinations: RD 96 2-95 × Fen, Mag 62 × RD 96 2-95, Toma-18 × Fora, BD 96-18 × Fen, Ivol D 96 × Fen, Ivol D 96 × Toma-18, Kozyr. Card × Mag-62. These hybrid combinations are a valuable breeding material for increasing yield.Item Correlation of yield with quality indicators for triticum Aestivum l. genotypes(CEP USM, 2024) Pravdziva, Iryna; Shadchyna, TamaraThis article presents correlations between yield and wide range of quality indicators of genotypes Triticum aestivum L. They include physical indicators of grain quality, flour and bread quality indicators as well as rheological properties of dough. A significant influence of growing conditions on the strength and direction of the relationship between yield and grain quality indicators is noted. A number of varieties and breeding lines of winter bread wheat have been identified, which combine in one genotype a higher level of yield with correspondingly high grain quality indicators, which should be used in practical breeding to create new basic material.Item Features of the technology of growing Allium ursinum L. in Ukraine(CEP USM, 2024) Pryvedeniuk, Nazar; Hlushchenko, LyudmylaThe possibility of growing Allium ursinum L., in the field conditions of the left bank forest-steppe of Ukraine has been established. Studies have been carried out to establish the influence of the density of Allium ursinum L., planting on the yield of dry leaves. A tendency to increase crop productivity with an increase in planting density has been revealed. The highest yield of dry raw materials among the studied variants was obtained with a planting density of 444 thousand plants/ha.Item Biological and agricultural characterization of introduced variety „Weiki” (Actinidia arguta planch) in Georgia(CEP USM, 2024) Bobokashvili, Zviad; Maglakelidze, Elene; Kvaliasvili, VazhaToday, the most important task of agricultural development, along with traditional crops, is to facilitate the introduction and testing of highly adaptive crops with a competitive advantage in the country, such as Kiwiberry.
